Baltimore City transportation officials said they will not fight more than 6,000 contested speed camera tickets because they don't have the data to stand up in court.

The embattled speed camera program is on hold while the city works out problems with the system. In the meantime, thousands of drivers will not be held responsible for fines that were received from speed and red light tickets in 2012, city transportation officials said.

About 6,000 ticketed drivers decided to fight their citations in court as questions were being raised about the reliability of the city's speed camera program.

"We don't want to take the judge's time. We don't want to take the citizens' time to come out just to find out that we don't have the information, so there's no point in wasting everybody's time. It's time to move ahead," said city Department of Transportation Director Frank Murphy.

He said the city doesn't have the sufficient data it needs to defend the citations in court.

Xerox was the city's vendor when the tickets were issued. Murphy said the company hasn't turned over all of the information that the city needs to proceed.

"They have some things that they believe that we owe to them, and we have some things that we believe they owe to us, but I really don't want to get into any more than that," Murphy said, citing legal matters.

The voided tickets mean hundreds of thousands of dollars in lost revenue. The money gained from uncontested tickets goes to the city. Money gained from tickets paid through the court process goes to the state.

But as the city moves forward with a new vendor and works to improve the now-suspended speed camera program, Mayor Stephanie Rawlings-Blake said that the lost revenue is not her primary concern.

"My concern is that we get this right. Because of an ongoing dispute with the previous vendor, we lack the proper evidence to go forward. But for me, this is about that we can move forward with a program that helps us reach our goal, which is to create safety for our kids," the mayor said.

Murphy said that Xerox has given the city a lot of data, just not everything it needs to proceed.
